I lMPRovEMENT INe SuLKY-PLows.

Specification forming part of Letters Patent No. 48,512, dated July-4, 1865.

To all whom t may concern: y i

y. Beit known that I, JAMES BREWER, of Albany',`in the county of Whiteside and State of" lllinois, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had t the accompanying drawings,'in whichi Figure l represents a perspectiveview of said sulky-plow. Fig. 2 represen ts a longitudinal vertical section through the same. Fig represents a cross-section through the linewb ot' Fig. 2. i

To enable others skilled in the art to make and use my invention, I will proceed to de.-

A represents the axle supported bythe standards B,`which are recessed,`and in whose recesses the spindle-blocks C are set and secured by means of the bolts c, which pass through the slots d of the standards B. blocks C are *provided with lugs g, through which screw-spindles j' pass, the latter being set into the axle A, and are provided with collars h, which, bearing against the plate i of the standard B and against the axle A, prevent any longitudinal motion of the screwspindle fi The upper ends of the latterare square to per- Init the application of a wrench for turning the spindles, and `when the screw-nuts c are loosened the plow-frame and the plow can be raised or lowered bodily, as desired.

E and F are beam-posts mortised into the axle A. The post F is rigidly secured to the axle and braced by means of the brace k. The

' post E is secured to it by means of bolt m, on

which it can turn. Both posts are braced against yielding toward the front or rear by means of the braces n. A screw-bolt, o, passes through the lower ends of the posts E F and projects beyond the yielding post E, and a spiral spring, p, is set upon the projecting part thereof and secured to it by means of the nut 2. The object of said spring is to allow the post E` and the plow-beaml to yield laterally if the plow should strike against anything too hard to be cut off, as will be more fully explained hereinafter. f

Gr represents the plow-beam. It is set be- The 'spindletween the two hangenposts E F, which keep it in its proper position. Its rear is supported by `a caster-wheel, H, and its front end plays between two hangers of the main frame, and is suspended to a rod, K, whose upper end is fastened toa foot-lever, L. Thus the pitch and depth of the plow can be adjusted by raising or depressing the front endof the plow-beam bymeans of the foot-lever L.

M represents the plow, secured to the beam- G by means of its standard N, and O a revolving root-cutter in front of the plow, as

' above stated. r The plow in striking a hard objectfsuch'as astone or stump-which it cannot cut, can yield, owing tothe yielding standard E,thus preventing breakage, and when the plow has passedthe obstruction the spring p forces the standard E back against the plowbeam, holding it again in its proper position. To facilitate the yielding of the plow I make the front end of the beam Ground, so that it can turn readily between the hangers I, and a friction-roll, q, bears againstV the ways infront oi' said hangers to facilitate the raising or depressing of the plow-beam, while any longitudinal movement of said beam is prevented by the pin r in the beam, which bears against the rear side of the said hangers I. The yielding post E can be fitted closely or loosely to the plow-beam by means ofthe adjusting-nut 3, and by adjusting the bolt m within the slot in the axle A, the springp may be removed entirely when it is desired to keep the plow-beam steady.-

0 O" represent the hounds of ,Iny pl0w,which 4 adjustable by having its fastening-bolts 4 passing through slots 8 in the axle A.. Thus thefurrow-wheel can be adjusted inward or outward according to circumstances. The hinge s, by which the furrow-hound O is fastened to the tongue P, is Slotted to permit of a longitudinal adjustment `of said hinge, .so that the hound can be moved forward or backward.

The hangers I, which straddle lthe front end of the plow-beam G, are provided with pinf holes 6, into which a pin can be inserted at the desired-height, by which said end can be retained to adjust the depth of the plow.

The caster-wheel H runs in the furrow immediately behind the plow. The spindle u of its caster is set into the caster-socket v,which latter is bolted to the lower side of theplowbeam by means of the iange 5. The holes in said flan ge, through which the fastening-bolts 7 pass,'are slotted to permit of said casterwheel being adj usted to conform to thelandside of the plow, and they-wheel can thus be accurately adjusted to support the plow properly and to relieve it 'of the entire friction arising from the dragging ot' the bottom of the plow in the furrow. To et't'ect the latter properly I apply washers, by which the caster-wheel H can be raised orlowered by insering them either vbelow or above the caster-socket o, andI am thus enabled to adapt the caster-wheel to the nature of the ground.

To make the plow cut more or less land the breast-yoke Q, which is swiveled to the front end of the pole P, is provided with holes 8, by means of which the pole or tongne can be moved from side to side.

Vhen the plow is intended to cut an ordinary furrow the tongue P will be tiastene'd in the center hole of the breast-yoke; but it' it is wished to out more or less of an ordinary furrow the. tongue will have to be thrown respect! ivelytto the left or to the right from' the center hole of the breast-yoke.

From the above description it will be seen that the plow-beam G works loosely between the posts E F, and for this reason is perfectly independent of the supporting-wheels R, and when saidV wheels run over rough ground the plow-beam will play up and down between the posts E F, leaving the plow runninglevel and steady, that the driver from his seat S can readily adjust the depth of the plow by treading on lever L, and can thus raise it from the ground altogether, and that the plow by means of its various adjustments is adapted to almost any kind of plowing and soil.

The hound Ol and its cross-bar are provided with suitable slots to permit of the movement vof the hounds above described.

Having thus fully described the nature of my invention, what I claim herein as new,and desire to secure by Letters Patent, is-

l. Making one of the standards E F, which keep the plow-beam in its proper position, yielding to a certain degree, forthe purpose of permitting the plow to pass obstructions which are in its line and which are too hard to cut, substantially as and for the purpose specified.

2. The combination, with the plow-beam, of

the rigid standard F, yielding standard E,

5; Connecting the hound on the furrow side to the pole by means of a hinge, s, for the purpose of making it and the furrow-wheel adaptable, as and for the purposes specified.

6. The combination,with the foot-lever L and I plow-beam G, when capable ot' rotation within the standards I, ot' the friction-rolls q, as and for the purposes specified.

7. In combination with the plow-beam Gand tongue I), the adjustable breast-yoke Q, for the purpose of cutting more or less land, as herein described.
